Cheap operating flashing FREDs
Posted by Noah Hofrichter on Thursday, April 22, 2004 4:32 PM
Does anybody know where I can find a cheap, track power flashing FRED, preferibly with a capacitor to hold power for a while when the track power is
off[?] I have seen a version that is perfect from Richmond Controls, but it's $35.00 + shipping. I was hoping maybe somebody might know of a cheaper version. Maybe there is a way I could make my own with a pre assembled and preprogramed for flashing circut board?

Any help would be appreciated,
Noah[?]

Two screws/nuts to mount slider switch(can be 2-56s ) which can be installed

Not being DCC, I had no choice in the matter, didn't want to get re-ended.

One can also do the same on a caboose, for a constant on red , just by getting a non-blinking led.

ADDENDUM:
On the caboose I use a smaller red led, 5mm, part# 276.209, insert it into
the rear wide railing into the caboose body. and connect to above assembly.

Also used the same idea in the rear roof of my Athearn 72' observation
end car by drilling a hole to seat the led and connect to the above assembly.

I am using a Sunrise FRED ($10) N Scale and building my own flashing circuit. The flashing ciruict will cost less than $1 in parts.

Jaybee sells a Flashing FRED for Athearn Cabooses that can easily be addapted to other freight cars. I think it listed for #12.00 and is described as being battery powered.
